M A Simmonds, J Richenbacher

    Journal of Pain and Symptom Management
    |April 1, 1992
    PubMed
    Summary

    Transdermal fentanyl patches offer a safe and effective noninvasive method for continuous pain relief in chronic cancer pain patients. This drug delivery system ensures steady fentanyl blood concentrations, improving pain management outcomes.

    Area of Science:

    • Pharmacology
    • Pain Management
    • Drug Delivery Systems

    Background:

    • Chronic pain, particularly cancer pain, necessitates continuous and effective pain relief strategies.
    • Alternative drug delivery routes are crucial for managing persistent pain experiences.
    • Transdermal drug delivery offers a noninvasive approach to sustained medication administration.

    Purpose of the Study:

    • To evaluate the safety, efficacy, and practicality of transdermal fentanyl for chronic cancer pain management.
    • To assess the relationship between transdermal fentanyl dosage and steady-state blood concentrations.
    • To determine the long-term effectiveness and patient tolerance of transdermal fentanyl therapy.

    Main Methods:

    • Review of early studies and a multicenter trial involving patients with chronic cancer pain using transdermal fentanyl.
    • Analysis of fentanyl dosage, plasma concentrations, and pain relief correlation.
    • Assessment of system wear time, dose titration, and need for supplementary analgesics.

    Main Results:

    • Transdermal fentanyl demonstrated a linear relationship between dose and steady-state blood concentrations.
    • Effective pain relief was achieved and correlated with plasma fentanyl levels.
    • The transdermal system was safe, effective, and well-maintained over extended periods (median 84 days).

    Conclusions:

    • Transdermal fentanyl therapeutic systems represent a significant advancement for noninvasive, continuous drug administration in chronic cancer pain.
    • This method provides a promising alternative for achieving effective and sustained pain relief.
    • The safety and clinical effectiveness of transdermal fentanyl are supported by cumulative patient experience.
